'Create node' works

- HAD TO CHANGE setActiveNode() in NetworkConfig.java to PUBLIC!!!!! I
had to call it in NetworkEngineer.java after adding a node that *was*
the active node.

-Did a lot of other crap with the NetworkEngineer.java &
NodeCreationPanel.java to make it work.

- I tested it a good deal. Seems to work. Let's debug on Monday cause
that's so much fun.
